OSCAR MILTON HUMPHREYS, 0F .A TCHELITZ, BREETISH COLUMBIA, CANADA.

Be it known that L'OsoAn MILTON HUM-1 PHREYS, a subject of the King of Great Britain, and a resident of Atchelitz, in the municipality of Chilliwack,in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Calendar-Clocks, of which the following is a specification.

My invention relates to improvements in calendar clocks, and the object ofmy inven tion is to devise a clock having a calendar incorporated therewith, which calendar is automatically operated-by suitable mechanism actuated by the clockmechanism, thus providing a clock whichnot only indicates the time but also the day, date, month and year as well and which is a great convenience for either business or household purposes. I attain this object by the means illustrated in the accompanying drawings in which Figure 1 is a front'view of the calendar as disposed within the clock case. Fig. 2 is aback view ofmy clock. Fig. 3 is a side view looking from the left hand in Fig. 1, the clock case being shown in section. Fig. 4 is a fragmentary side view looking from the right hand in Fig. 1, the clock case being shown in section. Fig.5 is'a fragmentary front view ofthe lower portion of my clock.

Fig. 6 is a face view of the gears for setting the calendar mechanism by means of the hour hand. Fig. 7 is a face view of the outer half of the middle gear in Fig. 6, showing theratchet shaped teeth.

' Application filed February 13, 1315. Serial No. 7,970.

To all whom it may concern: r

cured thereto'by the screws 11. Extending transversely between the frames 9 and 10 and secured therein are two pairs'of shafts 1213 and 1415, which shafts carry. rotatably the calendar rollers in' the following manner: Looking at the. front of'the clock, as 1n Fig. 1, the day roller 16, on which are printed the days of the week, is rotatably mounted onshaft 12 at the left hand side, which roller carries, ratchet fashion, on its lnner end a spring dog 17, and is provided at its opposite end with a milled wheel 18 and also has formed on its periphery adjacent the milled wheel seven ratchet shaped teeth, 4

indicated by the numeral 19, each of which teeth represents one day of the'week. On

the remaining portion of shaft 12 is rotatablymounted the date roller 20, to which is secured one end of a ribbon, 21in Fig. 4, on

which ribbon are printed the date s,as shown teeth 23, which are engaged by the dog 17 when roller 16 is turned in the direction of,

the arrow, as shown in Fig. 3, and over which.the dog 17 slipswhen the roller 16 is turned in the other direction.

Roller 22 is provided on its outer end with a plurality of ratchet shaped teeth 24, which are engaged by a spring dog similar-to the dog 17 and which dog is carried ori the inner face of a" milled wheel 26 rotatably mounted on shaft 13, as shown in Fig. 9, so that'when the milled wheel 26 is rotated in the direction of the arrow, as in Fig. 4, it will rotate the roller 22 in the corresponding direction, butwhen turned in the other direction its dog 25 will slip over the teeth 24 without rotating the roller 22 Rotatably mounted on the. shaft 13 at the opposite end from roller 22 isa milled wheel 27, whichengages' the milled wheel 18 of day roller 16, so that when the milled wheel 27 is rotated in one direction it will cause the milled wheel 18- and roller 16 to rotate inthe opposite direction. The peripheries of the milled wheels 26 and 27 project slightly through the back of the clock case 1, as shown in Fig. 2, so that they may be actuated by hand when required.

- at the left hand side, as in Fig. 1, is the month roller 28 provided at its outer end with a milled wheel 29, which roller 28 is in valinement with a plain roller 30 rotatably mounted on shaft 15, an endless ribbon 31 carrying'the respective months being passed tightly around the rollers 28 and 30 so as to move with same as they are rotated. On the remaining portion of shaft 14 is rotatably mounted the roller 32, which has the respective years printed thereon and is provided with a milled wheel 33. These rollers 28 and 32 are actuated by hand, the peripheries of their respective milled wheels 29 and 33 projecting through the bottom of the case 1 for this purpose, as shown in Fig. 1.

34 indicates a shaft rotatably supported by the frame 2, as shown in Fig. 3, one end of the shaft being carried through the back of the-case 1 and having a pointer 35 secured thereto, which pointer is provided with a foldable finger grip member 57, shown in Figs. 2'and 3, by means of which the pointer 35 and shaft 34 may be rotated at will for a purpose more fully hereinafter described.

The other end of shaft 34 is extended beyond the frame 2, and has secured thereon a gear 36, shown in Fig. 3 and also in Fig. 6.

Rotatably mounted on shaft 34 and in gear with the pinion 7 ,on' the clock spring I formed integrally with the body andoffset shaft 8 is a gear 37 carrying on its face a spring dog 38, as shown in Fig. 1, and similar tothe dogs 17 and 25. Secured to shaft 34 adjacent to gear 37 is a disk 39 carrying on its outer periphery a plurality of ratchet shaped teeth, in one of which the spring dog 38 of gear 37 is engaged so as to rotate the disk 39 when the gear 37 turns in the direction of the arrow in Fig. 1, but over which the dog slips when the gear 37 is moved in the opposite direction. Secured to the outer face of the disk '39 and near its edge are two pins 40 and 41, spaced a suitable distance apart, and which pins are provided for the purpose of raising the bar42, as more full; described hereinafter.

The bar 42 is slidably mounted in a vertical position on the frame 9, which frame is bent over at its upper end, as shown in Fig. l, a slot being provided in this bent over portion and in which slot the bar 42 operates. This slot is made larger than the bodyv I gaged at the proper time by the pin 40 to raise the bar the "required height, while at a suitable point below its upper end it has inwardly therefrom an outstanding wedge shaped portion 44, adapted to be engaged by the pin 41 when the bar has been raised sufficiently so as to press-the bar outwardly unpawl is then carried downwardly by the dropping bar 42 and out of the tooth 19.

of offset being such that the pin 41 will en- '70 gage the wedge shaped portion 44, as described, without extending into the path of the end 43 as it drops.

45 indicates a spring secured to frame 9 and bearing against the back of the bar 42, the purpose of which is to return the bar to its normal position afterit has been operated by the pins 40 and 41.

46 indicates a pawl swingably connected to the bar 42 at a, suitable point thereon, which pawl engages successively each of the seven teeth 19 of the day roller 16, as shown in Fig. 3, a spring 47 being provided for the purpose of keeping the pawl in engagement with the tooth when in its effective position. Extending between a lug 48 on the bar. 42 and a suitable part of the frame 9 is a spring 49, which spring is in tension when the bar is raised and operates to draw the bar downward when same is released from pin 40. A spring 60 is provided on bar 42, as shown in Fig. 3, which spring engages a projection 61 on the pawl 46 when it has moved the roller 16 the required amount so that it, the spring 61, will then bear on the pawl to disengage it from the tooth 19 of the roller when the bar is in its lowest position, thus permitting the turning of the roller 16 by hand to change the days up till the time the pawl is again engaged. in the succeeding tooth of the roller. With reference to'the action just described, it may be further-explained that, unless provision was made otherwise, the pawl 46 wouldremain in engagement with the tooth 19 after it had moved the roller 16 the desired amount, and thus the roller could not be turned backward by band to'change the days when required. To

overcome this, therefore, the bar 42 is designed to drop farther than is necessary to accomplish the actual turning of the roller, and, as it continues dropping, the inclination of the pawl changes until the projection 61 comes against the spring 60, whereupon the The gear 36, hereinbefore mentioned, on shaft 34, is actuated by means of a. double gear, so tospeak, represented by themiddle gear of Fig. 6. This gear consists of two gears 50 and 51 I respectively, .rotatably. mounted close together on shaft 52, which I shaft is secured to the frame 2'. Gear 50 is provided on its inner face with 'a plurality of ratchet shaped teeth 54;" as shown in Fig. 7, and gear 51 is provided on its inner face with a spring dog 53, as shown'in Fig. 8,; which is normally engaged by the teeth 54 so that when the gear 50 rotates in the direction of the arrow in Fig. 6 gear 51.wi11 1 hour hand pinion 6, while gear I of the clock case 1 and are covered with.

gear 50 is rotated in the opgear 51' will remain station- Gear 50 is normally engaged by the 51 normally engages the gear 36. on shaft 34.

Openings 55 are provided in 'the front rotate, but when posite direction ary.

glass" orother suitable material, through which openings the day, date, month, and year are at all times visible, asshown more particularly in Fig. 5. A graduated index 56 isarra-nged on the back of the case 1 and gears with the gear with .which the pointer 35 co-acts, the index being marked with the words Forenoon and. fAfterno onK shown-in'Fig; 2-, so" that the pointer may be set to any specified time, the purpose of which will become apparent from the fol-.

lowing description of. the operation of the device. I

I When the clock has, been wound up and started in the usual manner the pinion 7 turns once in 6 hours. As it-has eight teeth 37 which has thirtytwo teeth, it will-be seen that the gear 37,

and also the diskw39 with its pins 40 and 41'wil1 turn once in 24 hours. Now, assum- 'ing that the rollers are set correctly and 41 at th ,travel.

sharply downward by the spring" 49so that the pawl that the clock is'wound up andstarted at '12 oclock midnight with the pins 40 and e commencement of their 24 hour The disk'39 will then move during the daybringing' the pin 46 nearer to the end 43 of the bar 42 until at a certain time before the expiryof the 24 hours the pin 40will engage the end 43 and raise the bar upwardly as the disk 39 continues moving.

The distance between the pins 40 and 41 that when pin 40 has lifted the bar is such 42 to the highest point the pin 41 will have forced the bar outwardlyby pressing on the wedge shaped portion 44 until, co-incident with the completion ofthe 24 hours, the bar 42 will be forced clear .of pin 40 and pulled 46 will force the day roller 16 around to bring another day into view behind its opening 55. I

Simultaneously with the movement of the lay roller the date rolier'20 will be moved in advance the date by the spring dog 17 i hich engages theteeth .23'of the roller 20. This operation is I tion of each 24 hours, thatis at 12 oclock midnight, untilthe date ribbon 21 has been wound on be rewoun-d on toroller 22 again by turning the milled wheel 26 in the direction of the arrow in Fig. 2, the pawl 46 being first disengaged from the tooth 19 to permit of the free, simultaneous rotation of the day roller as the date roller 22 is rewound; The day roller 16' may be set backward at any time during the disengagement of the pawl 46 from the tooth of andfwith the hours, as

repeated at the comple to the front roller 20, when it may the roller, as hereinbefore described, by turning the milled wheel 27 by hand in the direction of the arrow in Fig. 2.

. Should the clock stop and then be set on again, it will be apparent that the pins 40 and 41 will. be out of their true relation to the time of their proper engagement with the bar 42, and re-adjustment is provided for by means of the index 56 and the pointer 35 secured to shaft 34. For instance, suppose the clock stopped at 3 oclock in the afternoon, the pins 40 and 41 would be in the position corresponding to that time and the pointer 35would indicate-3 oclock on the index. Now suppose the clock to be set on again at 9 oclock in the evening. At 12 oclock midnight the pins 40 and 41 would be 6 hours behind. However, when starting-the clock again the pointer 35 would beset at 2 on the index, which action would rotate sliaft 34' and disk vance the pins 40 and 41 to their true position with reference to the proper time for operating bar 42, at thesame time setting the hour hand correctlyby means of the gears shown in Fig. 6. I i

The provisionof the gear 36 and the gears 50 and 51, in engagement with the hour of the pins 40 and 41 by mean'sof the hour hand, as it will be 'se en that'by turning the hour hand 4 and pinion 6 forward the gears 50 and 51 will be rotated to rotate the gear 36 and thus the shaft ,34, the disk 39 and the pins 40 and 411ther eon. The hour hand maybe turned backward, if desired, to set the time irrespective of the calender, as it will be seen, will not then be rotated, since the pinion will'only rotate-the gear 50, the teeth 39 and thus a in that. case, that the shaft 34 54, of which will'slip over the dog 53 of gear51. 'In this manner provision is made for moving the hour hand independently of the calendar operating mechanism. Should,

however, the time be set/by moving thehonrhlle hand backward,- it is then necessary to move the disk 39 so that the pins 40 and 41 correspond as to their, position withthe corrected'time, and thisis done by moving the I shaft 34 by. means of the finger grip 57 of 'thes'pointer 35, the pointer then set at 'thetime on the index corresponding to the position of the hour hand of the clock. at I claim as my invention is In a calendar ol0ck,.the combination with ft'imeclpck having the usual clockwork mechanism, ofa suitably mounted day roller provided at its outer end with seven ratchet shaped teeth. arranged circularly equi-distant from each other, said roller carrying a spring dog" on its inner end, a pair of suitably mounted date rollers one of which is ed to be engaged by the spring'dog of the day roller, a date carrying ribbon wound on provided with ratchet, teeth adaptsaid rollers, and means co-acting with the teeth of the day roller'operated by the said clockwork mechanismifor imparting partial rotary movement to said roller at predetermined intervals.
